Definitions
- the invention relates to a scanning microscope with a lens that focuses an illumination beam on an object, a lens element upstream grid element, which is adjustable for time-varying deflection of the illumination beam to guide the focused illumination beam in a raster motion over the object, and a
- Image sensor on which the lens possibly in connection with further optics one
- Illuminated beam illuminated object emanates, wherein the image sensor has a plurality of individually readable by a control sensor elements over which the detection beam is guided in a movement corresponding to the raster movement of the focused illumination beam.
- At least one illumination beam is focused onto a sample by means of an objective.
- the objective is preceded by a raster element (such as, for example, one or more movable mirrors, an AOD, ie an Acousto Optical Deflector or the like), which deflects the illumination beam in such a way that that this on the sample the desired
- the grid element comprises one or more mirrors whose tilting movement is converted by the optical imaging into a lateral movement of the light spot generated on the sample by the illumination beam.
- the focused illumination beam thus scans the sample point by point.
- the detection light emanating from the sample is then detected for each halftone dot. Finally, the detection signal thus detected is assembled into an image in a computing unit.
- microscopy In the field of scanning microscopy confocal microscopy represents a particularly preferred microscopy method. The basic operation of this
- the confocal microscope 10 has a light source, not shown in FIG.
- Illuminating beam 12 on a dichroic beam splitter mirror 14 emits.
- the beam splitter mirror 14 is designed to emit light at the wavelength of the
- Illuminating beam 12 lets through.
- the illumination beam 12 thus passes through the
- Beam splitter mirror 14 and falls on a scanning mirror 16.
- a scanning mirror 16 As in Figure 1 by the
- the Abtastspiegel 16 is tilted. Due to the tilting movement of the scanning mirror 16, the illumination beam 12 is corresponding to the desired
- the illumination beam 12 After reflection on the scanning mirror 16, the illumination beam 12 passes through a
- the objective 22 finally focuses the illumination beam 12 onto a sample 24.
- the tilting movement of the scanning mirror 16 causes the focused image to scan
- Illumination beam 12 scans the sample 24 point by point.
- the latter is designed to reflect light at the wavelength of the detection beam 26.
- the beam splitter mirror 14 directs the
- Detection beam 26 thus on a lens 28, which focuses the detection beam 26 on a confocal aperture plate 30.
- a pinhole 30 is from the
- Detection beam 26 filtered out all the light that comes from areas of the sample 24, which originates outside the light spot generated by the illumination beam 12 on the sample 24.
- the light emanating from the sample 24 can thus be detected for each individual grid point and the detection signal thus generated can be combined to form an image.
- An essential feature of the confocal microscope 10 according to FIG. 1 in the present context is that the detection beam 26 emanating from the sample 24 is directed back to the scanning mirror 16, so that the detection beam 26 is influenced in the same way by the scanning mirror 16 As a result, the detection beam 26 is fixedly incident on the image sensor 32, while the illumination beam 12 is detected by the scanning movement of the scanning mirror 16
- the scanning mirror 16 in the confocal microscope according to FIG. 1 is arranged in a plane 36 which is one of those designated 38 in FIG. 1
- Object level represents optically conjugate level.
- Figure 1 are also a Intermediate image plane 40 and 42 shown.
- the intermediate image plane 40 corresponds optically to the plane 36 and is optically conjugate to the object plane 38.
- the intermediate image plane 42 corresponds optically to the object plane 38 and is optically conjugate to the plane 36.
- the detection light can be divided into different detection channels as differentiated as possible by wavelength. This is necessary, for example, in order to separate the detection signals originating from different dyes as well as possible from each other.
- different conditions in the sample can be detected by variations in the emission spectrum of a dye. If these variations can be measured by a well-resolved spectral detection, the user can reconstruct the different conditions in the sample.
- FIG. 2 shows the confocal microscope 10 in a modification which permits spectral detection.
- a dispersive element 44 is provided in the beam path downstream of the pinhole diaphragm 30, which decomposes the detection beam 26 into its different spectral components and supplies these components to the image sensor 32.
- the image sensor 32 has a multiplicity of sensor elements which can be individually read out via a controller 34.
- the various spectral components are illustrated in FIG. 2 by partial beams 26-1 to 26-7.
- the dispersive element 44 is preceded by a converging lens 46, which bundles the detection beam 26 passing through the perforated diaphragm 30 onto the dispersive element 44.
- the modification according to FIG. 2 utilizes the descanning principle used in the confocal microscope 10. Since the detection beam 26 leaves the pinhole 30 as a stationary beam, the various spectral components of the
- Detection beam 26 regardless of the currently imaged grid point on the sample 24 by the dispersive element 44 spatially separated from each other in the manner illustrated in Figure 2. For example, via a diaphragm not shown in FIG. 2, exactly the spectral component of interest can then be filtered out of the detection beam 26 and supplied to the image sensor 32.
- FIG. 3 shows a multiphoton microscope 50 in which a light source, not shown an illumination beam 52 on a tiltable Scanning mirror 54, on which the illumination beam 52 is reflected and then passes through a scanning lens 56 of focal length f3, a tube lens 58 of focal length f2, a dichroic beam splitter mirror 60 and finally a lens 62 of focal length f1 to focus on a sample 64 ,
- a detection beam 66 emanating from the sample 64 illuminated with the focused illumination beam 52 passes back into the objective 62 and is then directed by the dichroic mirror 60 to an image sensor 68 which is coupled to a controller 70.
- the scanning mirror 54 is located in a plane 72 which is optically conjugate to an image plane 74 in which the sample 64 is located.
- FIG 3 further levels 76 and 78 are shown.
- the level 76 represents a
- Object level 74 corresponds and is optically conjugate to the level 72.
- the detection beam 66 varies both in its angle of incidence and in its incidence on the image sensor 70 when the illumination beam 52 performs its raster motion on the sample 64.
- the spectral detection according to FIG. 2 is therefore not applicable to the confocal microscope 50 according to FIG. 3, which operates on the non-descanned principle.
- the object of the invention is a scanning microscope of the type mentioned so
- the invention solves this problem by the scanning microscope with the features of claim 1.
- a dispersive element of predetermined dispersion effect which separates the different spectral components of the detection beam spatially from one another on the image sensor, is provided in the scanning microscope.
- the controller detects the time-varying adjustment of the raster element, assigns the spatially separated spectral components of the detection beam in consideration of this adjustment, the sensor elements of the image sensor taking into account the
- the solution according to the invention provides for the spatial splitting of the detection beam, which is caused by the spectral separation by means of the dispersive element, to be separated from the spatial movement of the detection beam which is effected by the grid element.
- the controller detects the present adjustment of the raster element, that is, for example, the tilt angle of a raster element forming the raster element
- Scanning mirror assembly which may be formed of one or more mirrors.
- the controller also takes into account the previously known dispersion effect of the dispersive element. Based on this information, namely the adjustment of the
- dispersion effect of the dispersive element it may for example be kept in a memory, which is accessed by the controller, to the
- the dispersive element is disposed in a plane that is optically conjugate to a plane in which the sample is disposed.
- Element is preferably optically equivalent to a plane in which the grid element is arranged.
- optically equivalent is meant in this context that the two said planes correspond in a manner to each other optically, that the spatial variation of the illumination beam at the location of the grid element is translated into a corresponding spatial variation of the detection beam at the location of the dispersive element the spatial variation of the illumination beam at the location of the raster element in that the illumination beam varies in its angle of incidence, but not in its incident position, this also applies to the detection beam at the location of the dispersive element, ie also the detection beam varies its angle of incidence, but not its If the said optical equivalence is given in this sense, then it is particularly easy to realize the dispersive element suitably, since the incidence position of the detection beam at the dispersive element does not change.
- the raster element guides the illumination beam in a first
- the raster element is a single mirror that is rotated about a fixed axis to move the illumination beam preferably straight across the sample in the first scanning direction.
- the grid element can additionally illuminate the illumination beam in one of the first
- the raster element comprises, for example, two separate scanning mirrors, of which a first mirror, the raster movement in the first scanning direction and the second scanning mirror, the raster movement in the second
- Scanned direction causes. However, it may also be provided a single scanning mirror, which is moved in both scanning directions.
- the one scanning direction in which the illumination beam on the sample moves faster than in the other scanning direction will be referred to simply as a fast scanning direction. Accordingly, the other direction is referred to as a slow scan direction.
- the dispersion effect of the dispersive element is predetermined such that the spectral components of the detection beam are spatially separated on the image sensor in a direction perpendicular to a direction in which the detection beam is passed over the image sensor when the illumination beam in the first Scanning over the sample is performed.
- the dispersion effect of the dispersive element is predetermined such that the spectral components of the detection beam are spatially separated on the image sensor in a direction perpendicular to a direction in which the detection beam is passed over the image sensor when the illumination beam in the first Scanning over the sample is performed.
- the dispersive element generates a "spectral fan" in which the spectral information is encoded in an angle information
- the vertex of the scan angle of the raster element is preferably in the plane optically conjugate to the object plane, at the same time the scan angle is superimposed on the angle of the spectral splitting with respect to the slow scan direction, which means that in this embodiment the above-mentioned spectral fan is around that in the slow scan direction
- the spectral fan tilts back and forth with the scan angle relative to the fast scan direction, and the tilting motion in the fast scan direction is perpendicular to the tilt egung in the slow
- the dispersive element is located between the dispersive element and the image sensor detection optics, which bundles the spectrally split by the dispersive detection beam at each adjustment of the grid element in its entirety on the image sensor. Since it is to be ensured at all times that the detection beam, which performs a movement corresponding to the raster movement of the illumination beam on the image sensor and is also fanned out spatially by the dispersive element, falls in its entirety onto the image sensor, contributes a bundling detection optics of the aforementioned type at, not to let the image sensor too big.
- the detection optics is a lens in whose focal plane the dispersive element is arranged.

- a line sensor can be used as the image sensor.
- the detection optics comprises a crossed arrangement of three cylindrical lenses, the middle cylindrical lens of which
- the spectrally split detection beam can be particularly easily bundled on a line sensor independently of the currently present adjustment of the raster element.
- the controller may be configured to select at least one of the spectral components and to read only those sensor elements which are assigned to this selected spectral component. This allows a particularly efficient spectral detection.
- the dispersive element is, for example, a prism or a grating. However, it is not limited to such embodiments.
- an acousto-optical component such as an AOTF can also be used as a dispersive element.
- the solution according to the invention can be used profitably in any type of scanning microscope, but in particular in microscopes that work according to the non-descanned method, ie in which the detection beam is coupled to the image sensor before it reaches the grid element.
- a particularly preferred application is in multiphoton microscopy, in contrast to the confocal microscopy in favor of an improved signal-to-noise ratio is omitted, due to the detection beam to the grid element and then to pass through a pinhole. So will the
- Multiphoton microscopy often used in strongly scattering samples. As a result, the detection light is scattered so much that it no longer seems to originate from the central focus area. Nevertheless, this light should be captured by the image sensor to achieve a better detection signal.

- Sensor elements 124 which are individually readable by a controller 126.
- the dispersive element 120 is arranged in an intermediate image plane 128, which is optically equivalent to a plane 130 in which the scanning mirror 104 is located.

- the spatial variation of the detection beam 1 14 at the location of the dispersive element 120 corresponds to the extent of the spatial variation of the illumination beam 102 at the location of the scanning mirror 104.
- the detection beam 1 14 is thus at the location of the dispersive element 120 stationary.
- the dispersive element 120 has a predetermined dispersion effect, which results in the detection beam 1 14 being split into its different spectral components.
- the spectral components are in the representation of Figure 4 in the form of partial beams 1 14-1 bis 1 14-7 illustrates. Again, the partial beams 1 14-1 to 1 14-7 for the two tilt positions of the scanning mirror 104 shown in FIG. 4 are shown once with solid lines and once with dashed lines.

- it moves on the image sensor 122 in the y direction when the illumination beam 102 scans the sample 15 in the fast scanning direction.
- the image sensor 122 is preferably formed as a surface sensor due to the above-described movements of the detection beam 1 14, in which the individual sensor elements 124 are arranged like a matrix in rows (x-direction) and columns (y-direction). Since the sensor elements 124 arranged in a certain column (y-direction) each receive the same spectral component, the signals read out from the sensor elements 124 of this column can be integrated in the spectral detection.
- a line sensor may also be used as the image sensor 122.
- the detection optics 140 is configured to focus the sub-beams 1 14-1 to 1 14-7 on a single line. This can be realized, for example, with an arrangement of three cylindrical lenses. Also for the embodiment is in
- the lens 142 is designed as a cylindrical lens which has an effect on the detection beam 1 14 passing through it only in the x-z plane.
- two further cylindrical lenses 144 and 146 are provided, of which the lens 144 is upstream and the lens 146

- the cylindrical lenses 144 and 146 influence the passing through them detection beam 1 14 refractive effect only in the yz plane, as the representation of Figure 6 illustrates that shows a yz-section through the detection optics 140.
- the lenses shown in dashed lines thus act only on the axis oriented perpendicular to the plane of the drawing.
- the lens spacings can be achieved so that the detection beam 1 14, which passes through this crossed arrangement of the cylindrical lenses 142, 144, 146, in the y direction only in its angle of incidence, not but varies in its incidence position. This allows the use of a line sensor, ie a single-line detector, which detects the total amount of light at all times.
